:BATH-MACHINE.

Specification of Letters `latent No. 32,103, dated April 16, 1861.

To all 'whom it may :concern:

Be it known `that I, ALBERT "GUMMER, of Indianapolis, in the county of lWIarion and Stateof Indiana., have invented a new and useful Improvement in Lath-Machines; and I do hereby declare that the following is a full, clear, and eXact description ofthe construction and operation `of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view and Fig, 2 an end view.

The nature of my invention consists in the use of two distinct and separate rests for sustaining the bolt while it is being cut into laths, from those found in other machines, inasmuch that in one case, by the peculiar construction of the rests, a recess is formed, so as to admit ofthe falling `of the lath without obstruction, and in another by an arrangement of causing the two rests to recede from each other in a horizontal direction; also a provision for throwing out the lath.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction, and operation.

I construct my machine with a rectangular fra-me as shown at Figs. l and 2, and :lso )especially designated by the Figs.

(a, a) is the fly wheel fastened on one end of the shaft (b, 6,) and the cam (c) is fastened on the opposite end of the shaft (b, 5,) and working between the jaws (e, 6,) which form a part of the knife plate (f, f,) which slides to and fro in the slot (m, m).

(g, 9,) is the cross piece against which and `between the two guides (7L, h) the bolt to be cut into laths is placed.

(g,) and (an) are rests or supporters of the bolt. They are formed in the sha-pe of a right-angle and crossed at the outer points by another piece riveted on the top. The object of these pieces is to prevent the friction that would otherwise occur between the bolt and the rests, (f, f,) but the object of the right angled rest is to create a recess or space long enough to let the lath fall inside of the rests (g and n), after it is cut from the bolt. This peculiar form of the two rests (g) and (n) is particularly essential when bothof them are permanently bolted to the knife plate (f, f,) as they are supposed to be at pleasure. But atpresent only one is fastened so. Y

(0,) is a slot formed in the rest (g.)

(27,) is a pin `to work in the slot (0,) holding it stationary when the knife-plate f, is driven forward by the working of the -rest (g) on a oint and relieving it from contact with the bolt at the same time, and thus when the rest (p) is irmly attached to the knife plate (f, f,) it moves directly with the knife iplate and entirely out of the way of the falling lath, while the other rest (g) is held stationary or comparatively so at the same time, thus giving all the space possible for the lath to fall through without impediment, and by the returning of the knife plate (f, 7,) the two rests (g) and (a) are brought directly under the bolt again.

(la, k3) is a lever rest sliding lengthwise of the frame and in the end of which is the pin (u) which works in the slot of the lever this lever being attached. to the knife plate (f, f,) at its end (which moves in a diagonal direction by turning the fly wheel,) and carries with it one end of the lever while the other end is thrown in an opposite direction by means of the fulcrum pin (0),) which is fastened in the projecting piece (z',) and each one of the two `pins (11),) and (u) playsloosely up and down a separate slot for each pin, to accommodate the reciprocating and diagonal motion of the knife plate .i f, Thus it will vbe seen by this arrangement we are enabled to withdraw the rest (7c la) clearly out of the way of the lath, and relieving it from every impediment at the time of its being thrown out.

(3, 3,) is a jaw placed under the front edge of the knife which is bolted to the knife plate (f, 76,), the object of this jaw is to accommodate the spring (5) by forming a sort of shelf for the lath when it is being cut to slide upon and to keep the edge of it square against the spring which is intended to force out the lath after it is cut from the bolt, and to destroy the tenacity of the ber in holding on to something even after it is cut from the bolt. This spring is set between the jaw (3 3) and the under.

part of the knife and is made fast in the front edge of the knife plate (f f) and at the time of commencing to cut the lath the spring being of a circular form begins to assume a straight position, until the lath is cut when it rebounds, and in so doing throws off the lathe. But with reference again to the jaw (3 3,) vthere is yet another function to be spoken of which it performs, it may be used with or without the circular saring, (5,) in using it without the spring (5) it is simply necessary to extend the two projecting pieces (2, 2,2, 2,) as wide apart from each other as possible, then in that case the two set-screws (6, 6, 6, 6,) are slackened, and the jaw (3, 3,) is closed so as to pinch the lath and is held by the jaw (3, 3,) until the next lath is cut, which presses the former one up and it falls through between the projecting pieces (2, 2, 2, 2,) to the floor, and so on with all the others after it. S0 the difference in the two ways of shedding the lath from the bolt is first by means of the spring (5) throwing it forward, and the other is by means of the lath being forced by the cutting of it between the jaw and the edge of the knife when it is pressed up by the succeeding lath and finally falls to the floor in an opposite direction from that thrown out by the spring (5.)

at I claim and desire to secure by Letters Patent is- 1. The operation of the right-angled rest (g,) with the slot (0,) and the pin (29,) or their equivalents, as described.

2. The jaw (3, 3,) with the projecting pieces (2, 2, 2, 2,) the two set-screws (6, 6, 6, 6,) and the circular spring (5,) substantially as and for the purpose set forth.

ALBERT GUMMER.
